(2 /178) Ar-Razi (1/141) in Al-Fawa’id.

Shaykh Al-Albani (may Allah have mercy on him) graded this hadeeth as being Hasan. This is based on the Isnad that leads

Al-Alamah Muhammad Abdur Ra’uf Al-Manawee (may Allah have mercy on him) commented on this hadeeth saying, “First a person
should perform wudu which diminishes the anger. Then he should pray the two rak’ah.[ Faydul Qadir hadeeth # 3355]
